However, a Chinese indigenous breed, the Wugangtong goose (WGT), continues to be subject to selective breeding efforts as it displays segregation of plumage colors, including G, W, and a novel color pattern designated Wb (G with white breast circles). The underlying genetic mechanisms responsible for the Wb phenotype are yet to be determined.

Male and female Zhedong White Geese (ZDW) geese have long been selected for large body size and egg production, respectively. This led to a large difference in body weight between males and females, making them a unique model for studying the effects of sex on growth and development.

Background: Wernekink commissural syndrome (WCS) is a distinct midbrain syndrome that involves the caudal tegmentum of the midbrain and selectively damages the Wernekink commissure involved in the decussation of the superior cerebellar peduncle in midbrain. The aim of the study was to explore the clinical manifestations, imaging characteristics, and differential diagnosis of WCS in midbrain infarction to provide reference for clinicians in the diagnosis of WCS.
Case Summary: The clinical data of 4 patients with WCS with midbrain infarction were analyzed retrospectively.
Fatty liver syndrome (FLS), a common metabolic disease in laying hens, caused by excessive hepatic fat deposition is a bottleneck in the poultry industry. However, no specific therapeutic methods have been developed. Evidence suggests that microRNAs (miRNAs) are essential for liver lipid metabolism and homeostasis, providing strong evidence for targeting miRNAs as a potential treatment option for liver diseases.

Sixteen Y-chromosomal microsatellite markers, including seven newly identified loci, were used in the genotyping. The results showed that 4 out of the 16 loci were highly polymorphic in Chinese indigenous horse populations, in which the polymorphisms of 3 loci, ECAYP12, ECAYP13, and ECAYCAU3, were first reported in the present study.

In this study, three types of horse Y-chromosome markers, including Single-nucleotide polymorphisms (SNPs), copy number variants (CNVs), and allele-specific CNVs, were developed by screening more than 300 male horses from 23 indigenous Chinese horse populations and 4 imported horse breeds. Fourteen segregating sites including a novel SNP in the AMELY gene were found in approximately 53 kb of male-specific Y-chromosome sequences.

Methods: SNPs in 5'-UTR of eCG genes were screened across 10 horse breeds, including 7 Chinese indigenous breeds and 3 imported breeds using iPLEX chemistry, and the association between the serum eCG levels of 174 pregnant Da'an mares and their serum eCG levels (determined with ELISA) was analyzed.

The origin of domestic horses in China was a controversial issue and several hypotheses including autochthonous domestication, introduction from other areas, and multiple-origins from both introduction and local wild horse introgression have been proposed, but none of them have been fully supported by DNA data. In the present study, mitochondrial DNA (mtDNA) sequences of 714 Chinese indigenous horses were analyzed. The results showed that Chinese domestic horses harbor some novel mtDNA haplogroups and suggested that local domestication events may have occurred, but they are not the dominant haplogroups and the geographical distributions of the novel mtDNA haplogroups were rather restricted.
